Operation of each component
■Conditions affecting operation
The smart key system, wireless remote control and immobilizer s ystem use
weak radio waves. In the following situations, the communication between
the electronic key and the vehicle may be affected, preventing the smart key
system, wireless remote control and immobilizer system from operating prop-
erly. (Ways of coping: P. 527)
● When the electronic key battery is depleted
● Near a TV tower, electric power plant, gas station, radio stati on, large dis-
play, airport or other facility that generates strong radio wav es or electrical
noise
● When the electronic key is in contact with, or is covered by th e following
metallic objects
• Cards to which aluminum foil is attached
• Cigarette boxes that have aluminum foil inside
• Metallic wallets or bags
• Coins
• Hand warmers made of metal
• Media such as CDs and DVDs
● When other wireless keys (that emit radio waves) are being used nearby
● When carrying the electronic key together with the following devices that
emit radio waves
• Portable radio, cellular phone, cordless phone or other wirele ss commu-
nication devices
• Another vehicle’s electronic key, another electronic key of yo ur vehicle, or
a wireless key that emits radio waves
• Personal computers or personal digital assistants (PDAs)
• Digital audio players
• Portable game systems
● If window tint with a metallic content or metallic objects are attached to the
rear window

■If a warning message is displayed on the multi-information display
A system may be temporarily unavailable or there may be a malfu nction in
the system.
● In the following situations, perform the actions specified in t he table. When
the normal operating conditions are detected, the message will disappear
and the system will become operational.
If the message does not disappear, contact your Toyota dealer.
SituationActions
When the area around a camera is
covered with dirt, moisture (fogged
up, covered with condensation, ice,
etc.), or other foreign matterUsing the wiper and A/C function,
remove the dirt and other attached
matter. ( P. 370)
When the temperature around the
front camera is outside of the opera-
tional range, such as when the vehi-
cle is in the sun or in an extremely
cold environment
If the front camera is hot, such as
after the vehicle had been parked in
the sun, use the air conditioning sys-
tem to decrease the temperature
around the front camera.
If a sunshade was used when the
vehicle was parked, depending on
its type, the sunlight reflected from
the surface of the sunshade may
cause the temperature of the front
camera to become excessively high.
If the front camera is cold, such after
the vehicle is parked in an extremely
cold environment, use the air condi-
tioning system to increase the tem-
perature around the front camera.
The area in front of the front camera
is obstructed, such as when the
hood is open or a sticker is attached
to the part of the windshield in front
of the front camera. Close the hood, remove the sticker,
etc. to clear the obstruction.
When “Pre-Collision System Radar
In Self Calibration Unavailable See
Owner’s Manual” is displayedCheck whether there is attached
materials on the radar sensor and
radar sensor cover, and if there is,
remove it.

■Automatic reactivation of TRAC and VSC systems
After turning the TRAC and VSC systems off, the systems will be automati-
cally re-enabled in the following situations:
● When the power switch is turned off
● If only the TRAC system is turned off, the TRAC will turn on wh en vehicle
speed increases
If both the TRAC and VSC systems are turned off, automatic re-e nabling will
not occur when vehicle speed increases
■ Secondary Collision Brake operating conditions
The system operates when the SRS airbag sensor detects a collis ion while
the vehicle is in motion.
However, the system does not operate in any of the following si tuations.
● The vehicle speed is below 6 mph (10 km/h)
● Components are damaged
■ Secondary Collision Brake automatic cancellation
The Secondary Collision Brake is automatically canceled in the following situ-
ations:
●The vehicle speed drops below approximately 6 mph (10 km/h)
● A certain amount of time elapses during operation
● The accelerator pedal is depressed a large amount
■ Reduced effectiveness of the EPS system
The effectiveness of the EPS system is reduced to prevent the s ystem from
overheating when there is frequent steering input over an exten ded period of
time. The steering wheel may feel heavy as a result. Should thi s occur, refrain
from excessive steering input or stop the vehicle and turn the hybrid system
off. The EPS system should return to normal within 10 minutes.

■The system can be operated when
●The power switch is in ON mode.
● Intuitive parking assist function is on.
● The vehicle speed is less than about 6 mph (10 km/h).
● The shift lever is in other than P.
■ If “Parking Assist Unavailable Clean Parking Assist Sensor” is displayed
on the multi-information display
A sensor may be dirty or covered with snow or ice. In such case s, if it is
removed from the sensor, the system should return to normal.
Also, due to the sensor being frozen at low temperatures, a mal function dis-
play may appear or an object may not be detected. If the sensor thaws out,
the system should return to normal.
■ If “Parking Assist Unavailable” is displayed on the multi-infor mation dis-
play
Water may be continuously flowing over the sensor surface, such as in a
heavy rain. When the system determines that it is normal, the system will
return to normal.
■ Sensor detection information
●The sensor’s detection areas are limited to the areas around th e vehicle’s
front and rear bumpers.
● The following situations may occur during use.
• Depending on the shape of the object and other factors, the de tection dis-
tance may shorten, or detection may be impossible.
• Detection may be impossible if static objects draw too close to the sen- sor.
• There will be a short delay between static object detection and display
(warning buzzer sounds). Even at low speeds, there is a possibi lity that
the object will come within 1.0 ft. (30 cm) before the display is shown and
the warning buzzer sounds.
• It might be difficult to hear the buzzer due to the volume of the audio sys-
tem or air flow noise of the air conditioning system.
• It may be difficult to hear the sound of this system due to the buzzers of
other systems.
■ Objects which the system may not be properly detected
The shape of the object may prevent the sensor from detecting i t. Pay partic-
ular attention to the following objects:
● Wires, fences, ropes, etc.
● Cotton, snow and other materials that absorb sound waves
● Sharply-angled objects
● Low objects
● Tall objects with upper sections projecting outwards in the dir ection of your
vehicle

■Situations in which the syst em may not operate properly
Certain vehicle conditions and the surrounding environment may affect the
ability of a sensor to correctly detect objects. Particular instances where this
may occur are listed below.
● There is dirt, snow, water drops or ice on a sensor. (Cleaning the sensors
will resolve this problem.)
● A sensor is frozen. (Thawing the area will resolve this problem.)
In especially cold weather, if a sensor is frozen the sensor di splay may be
displayed abnormally, or objects, such as a wall, may not be detected.
● On an extremely bumpy road, on an incline, on gravel, or on gra ss.
● When vehicle horns, vehicle detectors, motorcycle engines, air brakes of
large vehicles, the clearance sonar of other vehicles or other devices which
produce ultrasonic waves are near the vehicle
● A sensor is coated with a sheet of spray or heavy rain.
● If objects draw too close to the sensor.
● When a pedestrian is wearing clothing that does not reflect ult rasonic waves
(ex. skirts with gathers or frills).
● When objects that are not perpendicular to the ground, not perpendicular to
the vehicle traveling direction, uneven, or waving are in the d etection range.
● Strong wind is blowing
● When driving in inclement weather such as fog, snow or a sandst orm
● When an object that cannot be detected is between the vehicle a nd a
detected object
● If an object such as a vehicle, motorcycle, bicycle or pedestrian cuts in front
of the vehicle or runs out from the side of the vehicle
● If the orientation of a sensor has been changed due to a collis ion or other
impact
● When equipment that may obstruct a sensor is installed, such as a towing
eyelet, bumper protector (an additional trim strip, etc.), bicy cle carrier, or
snow plow
● If the front of the vehicle is raised or lowered due to the car ried load
● If the vehicle cannot be driven in a stable manner, such as whe n the vehicle
has been in an accident or is malfunctioning
● When a tire chains or compact spare tire is used
●
When a sensor or the area around a
sensor is extremely hot or cold.

■Situations in which the system may operate even if there is no possibil-
ity of a collision
Instances of the RCTA function unnecessary detecting a vehicle and/or object
may increase in the following situations:
● When equipment that may obstruct a sensor is installed, such as a towing
eyelet, bumper protector (an additional trim strip, etc.), bicy cle carrier, or
snow plow
● When there are spinning objects near your vehicle such as the f an of an air
conditioning unit
● When water is splashed or sprayed a sprinkler
● Moving objects (flags, exhaust fumes, large rain droplets or sn owflakes, rain
water on the road surface, etc.)
●
When the parking space faces a street
and vehicles are being driven on the
street
● When the distance between your vehicle
and metal objects, such as a guardrail,
wall, sigh, or parked vehicle, which may
reflect electrical waves toward the rear
of the vehicle, is short
● When a vehicle passes by the side of
your vehicle
● When a detected vehicle turns while
approaching the vehicle
3384-5. Using the driving support systems
• When water droplets are flowing on the camera lens
• When the vehicle height is extremely changed (nose up, nose do wn)
• When tire chains is used
■ Situations in which the syst em may operate unexpectedly
● Even though there are no pedestrians in the detection area, som e objects,
such as the following, may be detected, possibly causing the re ar camera
detection function to operate.
• Three dimensional objects, such as a pole, traffic cone, fence , or parked
vehicle
• Moving objects, such as a car or motorcycle
• Objects moving toward your vehicle when backing up, such as fl ags or
puddles (or airborne matter, such as smoke, steam, rain, or sno w)
• Cobblestone or gravel roads, tram rails, road repairs, white lines, pedes- trian crossings or fallen leaves on the road
• Metal covers (gratings), such as those used for drainage ditch es
• Objects reflected in a puddle or on a wet road surface
• Shadows on the road
● In some situations, such as the following, the rear camera dete ction function
may operate even though there are no pedestrians in the detection area.
• When backing up toward the roadside or a bump on the road
• When backing up toward an incline/decline
• If the rear of the vehicle is raised or lowered due to the carried load
• If a bumper protector, such as an additional trim strip, is in stalled to the
rear bumper
• If the orientation of the rear camera has been changed
• If a towing eyelet is installed to the rear of the vehicle
• When the rear camera is obscured (dirt, snow, ice, etc. are at tached) or
scratched
• When water is flowing over the rear camera lens
• If there is a flashing light in the detection area, such as th e emergency
flashers of another vehicle
• When a tire chains is used
● Situations in which the rear camera detection function may be difficult to
notice
• If buzzer may be difficult to hear if the surrounding area is noisy, the vol-
ume of the audio system volume is high, the air conditioning sy stem is
being used, etc.
• If the temperature in the cabin is extremely high or low, the audio system
screen may not operate correctly.

■Operation of the air conditioning system in Eco drive mode
Eco drive mode controls the heating/cooling operations and fan speed of the
air conditioning system to enhance fuel efficiency ( P. 366). To improve air
conditioning performance, adjust the fan speed or turn off Eco drive mode.
■ Auto Glide Control
When Auto Glide Control operates, the AGC indicator light will illuminate.
● Auto Glide Control may not operate in the following situations:
• When the brake pedal is depressed
• When a shift position other than D is selected
• When the vehicle speed is approximately 10 mph (15 km/h) or lo wer
• When the vehicle is accelerating on a downward slope
• When the PCS (Pre-Collision System) is operating
• When the dynamic radar cruise control with full-speed range is operating
• When the Parking Support Brake system is operating
• When the TRAC or VSC system is operating
• When the TRAC or VSC system is disabled by pressing the VSC OF F
switch
■ Sport mode automatic deactivation
Sport mode is automatically deactivated if the power switch is turned off after
driving in sport mode. ● While driving in Eco drive mode with D
selected, releasing the accelerator
pedal will activate Auto Glide Control
under certain conditions. (Auto Glide
Control may activate before the acceler-
ator pedal is fully released.)
When Auto Glide Control operates, the
electric motor (traction motor) will be
controlled, reducing the deceleration
force and allowing the vehicle to coast,
enhancing fuel economy.
